Abstract (en)

[origin: EP0959391A2] An electrical contact part for supplying a bias voltage to a developing roller usable in a process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, which contains an electrophotographic photosensitive member, a developing roller for developing an electrostatic latent image formed on the electrophotographic photosensitive member, an electroconductive flange engaged to one end portion of the developing roller, a driving portion, provided at one end portion of the flange, for rotating the developing roller, the electrical contact part includes (a) a connecting portion electrically connectable with a cartridge side electrode which is provided in the process cartridge and which is connectable with a main assembly side electrode provided in the main assembly of the apparatus when the process cartridge is detachably mounted to the main assembly of the apparatus; and (b) a projected portion projected at a side opposite from a side at which the connecting portion is connectable to the cartridge side electrode and insertable to between the flange and the driving portion. <IMAGE>
